Abstract

1. A process for purifying smoke gases containing SO2 , - in which the smoke gases are washed in two subsequent stages with aqueous absorption-solutions which had been made to circulate, an aqueous limestone-suspension being used in the first stage, and - in which the reaction products of the second stage are introduced into the washing liquid of the first stage, characterized by the use of an aqueous NaOH, KOH, Mg(OH)2 or NH4 OH solution as an absorption solution in the second stage.
